My take too. No way I’m volunteering to be vaporized.
I heard an opposite opinion a long time ago challenging that position that still bothers me, and I don’t have an answer for it: Not one atom or molecule that was in our bodies ten years ago is still in it. They’ve all been recycled. So in a sense, we’re already a copy of something that existed in the past and doesn’t exist any longer.
Actually that’s a pretty interesting thought. It seems that the only thing that’s permanent is our consciousness.
A human being is more than matter. The atoms in a person’s body and brain may change over time, but the real you isn’t generated by your body or your brain. The real you exists outside of space and time; your brain and body are the means by which you interface with space and time. Should your body suffer enough damage, it will cease to function, but you will carry on.
And don’t be confused between what things seem to be and what they are. The physical aspects of a human being (his or her “accidents”) can and do change with time, but the person behind those accidents (his or her “substance”) cannot change, since it exists outside of time.
